我有一个代码可以在表格中显示数据以及分页，但是代码在mysql中
<?php
include('config.php'); //include of db config file
include ('paginate.php'); //include of paginat page
$per_page = 10; // number of results to show per page
$result = mysql_query("SELECT * FROM subcategory");
$total_results = mysql_num_rows($result);
$row = mysql_fetch_assoc($result);
$total_pages = ceil($total_results / $per_page);//total pages we going to have
//-------------if page is setcheck------------------//
if (isset($_GET['page'])) {
$show_page = $_GET['page']; //it will telles the current page
if ($show_page > 0 && $show_page <= $total_pages) {
$start = ($show_page - 1) * $per_page;
$end = $start + $per_page;
} else {
// error - show first set of results
$start = 0;
$end = $per_page;
}
} else {
// if page isn't set, show first set of results
$start = 0;
$end = $per_page;
}
// display pagination
$page = intval($_GET['page']);
$tpages=$total_pages;
if ($page <= 0)
$page = 1;
?>
<!doctype html>
<html lang="en">
<head>
</head>
<body>
<?php
$reload = $_SERVER['PHP_SELF'] . "?tpages=" . $tpages;
// display data in table
echo "<table class='tablesorter' cellspacing='0'> ";
echo "<thead>
<tr>
<th></th>
<th>Subcategory Name</th>
<th>Category Name</th>
<th>Edit</th>
<th>Delete</th>
</tr>
</thead>";
for ($i = $start; $i < $end; $i++)
{
if ($i == $total_results)
{
break;
}
// echo out the contents of each row into a table
echo "<tr " . $cls . ">";
echo '<td></td>';
echo '<td>' . mysql_result($result, $i, 'subcatname') . '</td>';
echo '<td>' . mysql_result($result, $i, 'catname') . '</td>';
echo "</tr>";
}
// close table>
echo "</table>";
// pagination
echo '<div class="pagination" style="margin-left:300px;" >';
if ($total_pages > 1)
{
echo paginate($reload, $show_page, $total_pages);
}
echo "</ul>
</div>";
?>
</body>
整个代码在同一页上，现在我试图将其转换为mysqli，并且还为表中的每一行插入编辑和删除功能。
我拥有的新代码是
<?php
include('config.php'); //include of db config file
include ('paginate.php'); //include of paginat page
$per_page = 10; // number of results to show per page
$result = mysqli_query($con,"SELECT * FROM subcategory ");
$total_results = mysqli_num_rows($result);
$row = mysqli_fetch_assoc($result);
$total_pages = ceil($total_results / $per_page);//total pages we going to have
//-------------if page is setcheck------------------//
if (isset($_GET['page'])) {
$show_page = $_GET['page']; //it will telles the current page
if ($show_page > 0 && $show_page <= $total_pages) {
$start = ($show_page - 1) * $per_page;
$end = $start + $per_page;
} else {
// error - show first set of results
$start = 0;
$end = $per_page;
}
} else {
// if page isn't set, show first set of results
$start = 0;
$end = $per_page;
}
// display pagination
$page = intval($_GET['page']);
$tpages=$total_pages;
if ($page <= 0)
$page = 1;
?>
<!doctype html>
<html lang="en">
<head>
</head>
<body>
<?php
$reload = $_SERVER['PHP_SELF'] . "?tpages=" . $tpages;
// display data in table
echo "<table class='tablesorter' cellspacing='0'> ";
echo "<thead>
<tr>
<th></th>
<th>Subcategory Name</th>
<th>Category Name</th>
<th>Edit</th>
<th>Delete</th>
</tr>
</thead>";
for ($i = $start; $i < $end; $i++)
{
if ($i == $total_results)
{
break;
}
// echo out the contents of each row into a table
echo "<tr " . $cls . ">";
echo '<td></td>';
echo '<td>' . mysql_result($result, $i, 'subcatname') . '</td>';
echo '<td>' . mysql_result($result, $i, 'catname') . '</td>';
echo "<td><a href=\"a_edit_subcategory.php?id=".$row['id']."\"><input type='image' src='images/icn_edit.png' title='Edit'></a></td> ";
echo "<td><a onclick=\"return confirm('delete this record?')\" href=\"a_del_subcategory.php?id=".$row['id']."\" ><input type='image' src='images/icn_trash.png' title='Trash'></a></td> ";
echo "</tr>";
}
// close table>
echo "</table>";
// pagination
echo '<div class="pagination" style="margin-left:300px;" >';
if ($total_pages > 1)
{
echo paginate($reload, $show_page, $total_pages);
}
echo "</ul>
</div>";
?>
</body>
但是问题是我无法正确转换它，并且编辑和删除功能不起作用，即
echo '<td>' . mysql_result($result, $i, 'subcatname') . '</td>';
echo "<td><a href=\"a_edit_subcategory.php?id=".$row['id']."\"><input type='image' src='images/icn_edit.png' title='Edit'></a></td> ";
echo "<td><a onclick=\"return confirm('delete this record?')\" href=\"a_del_subcategory.php?id=".$row['id']."\" ><input type='image' src='images/icn_trash.png' title='Trash'></a></td> ";
最佳答案
尝试这个：
for ($i = $start; $i < $end; $i++)
{
if ($i == $total_results)
{
break;
}
mysqli_data_seek($result, $i);
$data = mysqli_fetch_assoc($result);
// echo out the contents of each row into a table
echo "<tr " . $cls . ">";
echo '<td></td>';
echo '<td>' . $data['subcatname'] . '</td>';
echo '<td>' . $data['catname'] . '</td>';
echo "<td><a href=\"a_edit_subcategory.php?id=".$data['id']."\"><input type='image' src='images/icn_edit.png' title='Edit'></a></td> ";
echo "<td><a onclick=\"return confirm('delete this record?')\" href=\"a_del_subcategory.php?id=".$data['id']."\" ><input type='image' src='images/icn_trash.png' title='Trash'></a></td> ";
echo "</tr>";
}
